Boa Island, at the northern end of Lower Lough Erne, is connected to the mainland at both ends – the main A47 road runs along its length. Spooky, moss-grown Caldragh graveyard, towards the western end of the island, contains the famous Janus Stone. Perhaps 2000 years old, this pagan figure is carved with two grotesque human heads, back to back.
The churchyard at Killadeas, 11km north of Enniskillen on the B82, contains several unusual carved stones. Most famous is the 1m-high Bishop's Stone, dating from between the 7th and 9th centuries, which has a Celtic head reminiscent of the White Island figures carved on its narrow western edge, and an engraving of a bishop with bell and crosier on the side.
